Answer:

19 i think

Step-by-step explanation:

the problem describes an isosceles triangle by saying that two sides are congruent

You can also infer that <T is the vertex so subtract that from 180 to find what the combined two missing angles are

you get 38, now divide that by 2 to find the missing angle

I have to find the angle measurements of a interior triangle a is 4x b is 7x-2 and c is 5x-10
RSB [31]

Answer:

m\angle a=48^o\\m\angle b=82^o\\m\angle c=50^o

Step-by-step explanation:

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

m\angle a+m\angle b+m\angle c=180^o

substitute the given values

4x^o+(7x-2)^o+(5x-10)^o=180^o

solve for x

(16x-12)^o=180^o

16x=180+12\\16x=192\\x=12

Find the angle measurements

m\angle a=4(12)=48^o

m\angle b=7(12)-2=82^o

m\angle c=5(12)-10)=50^o

What is the volume of the composite figure? Express the
Papessa [141]

Answer:

V=312\pi\ mm^{3}

Step-by-step explanation:

we know that

The volume of the composite figure is equal to the volume of a semi-sphere plus the volume of the cone

so

V=\frac{4}{6}\pi r^{3} +\frac{1}{3} \pi r^{2} h

we have

r=6\ mm

h=14\ mm

substitute

V=\frac{4}{6}\pi (6)^{3} +\frac{1}{3} \pi (6)^{2} (14)

V=144\pi +168\pi

V=312\pi\ mm^{3}
